Neurorehabilitation and Neural Repair
This study investigated whether a mismatch between perceived balance confidence and actual balance performance is associated with falls in people with Parkinson’s disease (PwPD). Falls are common in Parkinson’s disease, yet traditional predictors such as motor severity or balance test scores alone do not fully explain fall risk. The authors proposed that discordance between perception and performance may be a key factor.
Data from five pooled studies involving 244 PwPD were analyzed. Objective balance ability was measured using the Timed Up and Go (TUG) test, while perceived balance confidence was assessed with the Activities-Specific Balance Confidence (ABC) scale. A discordance score was calculated by comparing reported confidence with confidence predicted from TUG performance. Retrospective fall history over 6–12 months was examined.
Results showed that balance discordance was the strongest predictor of falls, even after adjusting for age, sex, disease severity, and objective balance performance. Including discordance significantly improved fall prediction. The study concludes that assessing both balance ability and perception—and their alignment—may improve fall risk identification and guide targeted interventions in Parkinson’s disease.
